单选题Snow Ranger The two things—snow and mountains—which are needed for a ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain—often called White Death. It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937—1938 at Aha, Utah, in Wasatch National Forest. This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a major ski area. Thus, development of Aha and other major ski resorts in the west was dependent upon controlling the avalanche. The Forest Service set out to do it, and did, with its corps of snow rangers. It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber. He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better. He studies snow, terrain, wind and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down. The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety for people on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, or talks with the ski area's operator as he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes.

单选题Travel Across Africa 1 For six hours we shot through the barren(荒芜的)landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I'd bought in a market in Mozambique. 2 Southern Africa was full of stories. And visions. We were almost drunk on sensations. The roaring(咆哮)of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana. 3 And then the other things: dogs in the streets, whole families in Soweto living in one room a kilometre from clean water. 4 As we drove towards the setting sun, a quietness fell over us. The road was empty—we hadn' t seen another car for hours. And as I drove, something caught my eye, something moving close enough to touch them, to smell their hot breath. I didn't know how long they had been there next to us. 5 I shouted to Dan : "Look !" but he was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. 6 When Daniel woke up an hour later I told him what had happened. 7 "Wild horses?" he said. "Why didn't you wake me up, Sophia?" 8 "I tried. But they were gone after a few seconds. " 9 "Are you sure you didn't dream it'?" 10 "You were the one who was sleeping!" 11 "Typical , "he said. "The best photos are the ones we never take. " 12 We checked into a dusty hotel and slept the sleep of the dead.

"I am {{U}}(51) {{/U}}," admits the Brazilian superstar. "But everyone has got a different kind of beauty. What I {{U}}(52) {{/U}} have is charm." Indeed he has. His buck teeth, flowing hair, big smile, and of course his {{U}}(53) {{/U}} skills are always eye-catching on the pitch. The 23-year-old striker scored two goals in a 3-2 win over Deportivo La Coruna on March 1. It was BarCelona's sixth win in a row and, thanks to their Brazilian's 10-goal contribution, {{U}}(54) {{/U}} looked like a poor season could now end a success. Ronaldinho - full name Ronatdo De Assis Moreira - is one of many South Americans who learned their skills playing in the backstreets before {{U}}(55) {{/U}} them off on the world stage. Great things were {{U}}(56) {{/U}} when Gremio signed him as a seven-year-old, and he soon became friends with Ronaldo, who was then the other young star of Brazilian football. It was Ronaldo who first called him Ronaldinho, which {{U}}(57) {{/U}} Little Ronaldo, and the name stuck.

"I have never failed to deliver in big matches," Ronaldinho says. "My game is based on {{U}}(60) {{/U}} . Often a forward does not have the time to decide whether to shoot or pass. It is instinct that gives out the orders." While he may not have David Beckham's good looks, Ronaldinho has a {{U}}(61) {{/U}} reputation off the pitch. At former club Paris Saint Germain, which sold him to Barcelona, he broke {{U}}(62) {{/U}} rules by going out and enjoying the city's nightlife. "Without doubt, Ronaldinho is the most {{U}}(63) {{/U}} player I have ever come across," says former PSG coach Luis Ferdandez. "The main {{U}}(64) {{/U}} for any coach is that one player without discipline can hurt the whole team." But Ronaldinho doesn't think he has done anything wrong. "I am just a young person who enjoys {{U}}(65) {{/U}}," he says.

单选题Some Things We Know about Language Many things about language are a mystery, and many will always remain so. But some things we do know. First, we know that all human beings have a language of some sort. There is no race of men anywhere on earth so backward that it has no language, no set of speech sounds by which the people communicate with one another. Furthermore, in historical times, there has never been a race of men without a language. Second, there is no such thing as a primitive language. There are many people whose cultures are undeveloped, who are, as we say, uncivilized, but the languages they speak are not primitive. In all known languages we can see complexities that must have been tens of thousands of years in developing. This has not always been well understood; indeed, the direct contrary has often been stated. Popular ideas of the language of the American Indians will illustrate. Many people have supposed that the Indians communicated in a very primitive system of noises. Study has proved this to be nonsense. There are, or were, hundreds of American Indian languages, and all of them turn out to be very complicated and very old. They are certainly different from the languages that most of us are familiar with, but they are no more primitive than English and Greek. A third thing we know about language is that all languages are perfectly adequate. That is, each one is a perfect means of expressing the culture of the people who speak the language. Finally, we know that language changes. It is natural and normal for language to change; the only languages which do not change are the dead ones. This is easy to understand if we look backward in time. Change goes on in all aspects of language. Grammatical features change as do speech sounds, and changes in vocabulary are sometimes very extensive and may occur very rapidly. Vocabulary is the least stable part of any language.

单选题The Spanish Flu Epidemic If you"re worried about the possibility of a coming bird flu epidemic, you can take comfort in the fact that humanity has survived a similar influenza epidemic in the past. Starting its rounds at the end of World War I, the 1918 flu killed an estimated 50 million people. Popularly known as the Spanish Flu, this type of influenza was far worse than your common cold. Normally, influenza only kills those who are more vulnerable to disease, such as newborns, the old or the sick. However, the Spanish Flu was prone to killing the young and healthy. Often it would disable its victims in hours; within a day, they would be dead, typically from extreme cases of pneumonia (肺炎). The Spanish Flu was quite nasty-fast-spreading and deadly. It managed to spread across the globe, devastating the world. Then suddenly, after two years ravaging (蹂躏) the earth, it disappeared as quickly as it had arisen. Despite its nickname, the Spanish Flu did not originate in Spain. Its true origins are unknown. Some believe it started in US first and then spread to Europe as America joined the war; others think that it populated the trenches of the English and the French and eventually broke out in 1918. Regardless of where it started, eventually a fifth of the world population suffered the disease, with a global mortality rate (死亡率) estimated at 2.5% of the population. Modernity was partly to blame for the quick spread of the disease. It passed throughout the world on trade routes and shipping lines. It hit Northern America, Europe, Asia, Africa and the South Pacific. The war did not help at all-the movement of supplies and troops aided the spread of the Spanish Flu, as well as the trench warfare. Imagine the speed at which a virus can spread in a crowded ditch. The fast emergence of the virus in the trenches caused some soldiers to believe that the Spanish Flu was a new form of biological warfare. Luckily, the Spanish Flu simply vanished by 1920. It is believed the flu simply ran out of fuel to spread.
